Kimi K3: Moonshot AI's 2.8T Parameter Model Released Free

Moonshot AI has launched a new model called Kimi K3, which they say is the largest AI model with open weights to date. This model has 2.8 trillion parameters. You can try K3 now through the Kimi app on iOS and Android, the kimi.com website, or the Kimi Work desktop app. No developer account is needed for the free tier, though there are usage limits. K3 uses a Mixture-of-Experts architecture and has a 1-million-token context window. It also supports images and reportedly video. Early benchmarks show it is competitive, performing well in tasks like coding and knowledge work. API pricing starts at $3 per million input tokens. Moonshot plans to release the full model weights on July 27, which will allow developers to download, run, and fine-tune it locally. This could significantly impact open-source AI development.
